Y., ASSIGNOR TO DYEING PROCESSES CORPORATION, OFNEW YORK, N. Y., A CORPORATION OF NEW YORK YARN HOLDER Applicationfiled. January 9, 1926. Serial No. 80,316.

The present invention relates to improvements in yarnholders forsupporting and retaining thereon in proper form yarn or similar textilematerial in the form of a cop. spool, bobbin or cheese or other form ofpackage during the process of dyeing or treating the yarn with a dyeingor other fluid.

One of the primary objects of the invention is toprovide a novel andimproved pervious holder of this class wherein the surfaces thereofwhich support the yarn are of relatively small area with respect to theinner cylindrical surface of the opening in the 15 yarn, thus enablingthe yarn on the holder to be compressed by the application of axialpressure at its ends, incident to the forming of fluid-tight connectionsfor the dyeing or treating liquor-to be forced through the yarn duringthe dyeing or, treating operation, whereby the dyeing or treating liquorWill be .caused to pass through the yarn in such manner as to insureuniform and level dyeing or other desired treatment.

Another object of the invention is to provide a previous holder of thisclass wherein the surfaces thereof which support the yarn are straightand continuous or without interruption throughout the yarn engaginglength of the holder, so that no obstructing edges or openings exist inthe surface, and, hence, the yarn which engages these surfaces will notcatch thereon while the holder is cop, spool, bobbin or cheese, or otherform of package, but will pass into or out of the package substantiallywithout friction and without injury to the yarn, thus facilitating thesubstitution of a paper, wooden or other holder forthe pervious holder,or vice versa. Another object is to provide a novel and improvedconstruction for a holder of this general class whereby great strengthand rigidity are attained, the surfaces which support the yarnor othermaterial comprising longitudinal members, the ends of which are fixedand secured firmly by the clamping action produced andmaintainedbetweenan outer memberwhich is under tension and an inner member.

being inserted into or removed from the Another objectof the inventionis to provide a pervious holder for yarns and other materials onto whichthe yarn or material may be transferred from a paper, wooden or otherholder preparatory to dyeing or other treatment, after which the yarn ormaterial may be readily removed from the holder to a paper tube or awooden or other substitute holder.

Further objects of the invention are to provide a method whereby aprevious holder of any suitable kind may be readily inserted in the yarnpackage as a substitute for a paper, wooden or other holder, thusfacilitating the preparation of the yarn for dyeing or other treatment,and to provide a method whereby a pervious holder may be readilyinserted in the yarn package as a substitute for. a paper tube or awooden or other holder preparatory to the dyeing orother treatment 79 ofthe yarn, and after such dyeing or other treatment has beenaccomplished, the pervious holder may be easily and quickly removed fromthe yarn package and a paper tube or a wooden or other holder insertedor substituted.

The present invention provides a holder which is applicable generally tovarious uses where it is desirable to support a material during thehandling thereof or the performance of operations thereon. The inventionis especially applicable to yarn holders of the general class used inyarn dyeing machines to support the yarn while in wound form so that thedyeing liquor may be forced through the yarn to dye it, although suchholders, it will be understood, may be used in other situations wherematerials of different kinds, especially textile materials, are to besupported in a manner to enable a treating fluid to be passed into orthrough them. The preferred embodiments of the invention are shown inthe accompanying drawings and will be hereinafter described in detail,but it is to be understood that the invention is not restricted to theprecise constructions shown as equivalent constructions arecontemplated, and such will be included within the scope. of the claims.

In the embodiment of the invention shown in Figures 1 to 3, inclusive,the holder comprises a suitable number of circumferentially spacedsupporting members 1 which extend in parallelism longitudinally of theholder so that their outer or peripheraledges which are to serve assupporting surfaces for yarn or other material placed'thereon coincidewith the circumferentially spaced lines of a cylinder. the diameter ofwhich substantially equals the diameter of the hole or bore in thepackage of yarn or material to be placed thereon. In order to securelightness of weight and rigidity as well as to facilitate themanufacture of the holder, these supporting members arepreferably-constructed from strips of sheet metal which are folded ordoubled transversely into channel form, the flanges of the supporting.members when i thus formed, serving to stiffen these members radially ofthe holder.

The supporting members are mounted and secured at each end of the holderon an inner ring 2 which is preferably made of an endless band' of metalof suitable thickness. This ring is provided with slots 3 which extendinwardly from its opposite edges and are located to properly receive theflanges of the supporting members. Preferably, the flanges of eachsupporting member are formed with tongues or lugs 4 which are adapted.to enter the slots 3 in the inner ring and the flanges between thesetongues are notched, as at 5, to receive the portions of the ring whichintervene the slots 3. As shown in the present instance, the tongues 4of two adjacent supporting members enter each pair of alined slots 3 inthe ring. The ends of the supporting members, at each end of the Iholder, are encircled by an outer ring or band 6 which may have aninturned flangethereon to part-1y overlie the ends of the supportingmembers, as shown. The parts of the holder are so constructed andassembled that the ends of the supporting members will be firmly held bya clamping action produced between the inner ring 3 and the outer ring6, which latter is under tension and has a tendency to contract. Thisclamping action may be produced by expanding, by a tube expander, .orother means, the inner ring 3. after all of the parts of the holder havebeen assembled, the resulting expansion of the ring 3 forcing the endsof the supporting members outwardly against the outer ring 6. thusputting the latter under tension, so that it exerts a compression on theinner ring.

In this construction, the slotted inner rings in cooperation with thetongues on the supporting members secure the supporting members inproper circumferentially spaced rethe inner ring, and the outer ring,which is under tension, and tends to contract, binds the supportingmembers firmly in position and avoids the. development of looseness.which, if permitted to occur, would result in relative displacement ofthe supporting members or other parts of the holder.

In using a holder constructed as just described the yarn in wound orpackage. form may be transferred from a paper, wooden or other holderonto the holder shown by pushing the package axially over one of theouter rings 6, and this may be done without difficulty by making theouter diameter of the rings 6 equal to the diameter of the paper, woodenor other holder from which the yarn package is to be transferred.Holders .as described, and on which yarn packages ments of the machinewhich exert axial compression on the yarn package and thereby formfluid-tight joints to enable thedyeing liquor to be forced through thepackage of yarn. The Compression to which the yarn packages are thussubjecteddoes not interfere with the uniform dyeing of the yarn as theyarn on each holder is engaged only'by the limited areas formed by theedges of the circunifcrentially spaced supporting members so that thedyeing liquor may flow freely through the central interior axiallyextendmg chamber or passageway formed within the circular series ofsupporting members, then outwardly through the spaces between thesupporting members. and through the package of yarn, or vice versa,substantially without obstruction by the supporting members.

Holders constructed as shown in Figures 1 to 3, inclusive. may be usedadvantageously in the dyeing or other treatment of packages of yarnandothcr textile materials, but after the packages of yarn have beendyed or treated on such holders, the yarn cannot be removed therefromunless by unwinding. Figures 4. 5 and 6 illustrate another embodiment ofthe. invention whereby removal of the yarn packages from the holderafter dyeing or treatment, as well as insertion of the holder into thepackage, may be accomplished quickly and with facility and without thenecessity of unwinding the yarn. In this embodiment of the invention theholder comprises a suitable number of supporting members 6 which aresuitably spaced circumferentially of the holder and extend inparallelism longitudinally thereof, they thus forniing a centralinterior chamber or passageway within the holder, the outer edges ofthese supporting members coinciding with lines extending axially of acylinder, thediameter of which approximately equals the hole or bore ofthe packages of yarn which the holder is to receive. These supportingmembers, as in the preceding instance, are preferably formed of stripsof sheet metal-doubled or folded transversely to secure strength andlightness in weight, and the ends of the supporting members are firmlyand immovably held by a clamping action produced and acting between aninner ring 7 and an outer ring 8 which is under tension and tends tocontract. Preferably, the flanges of each supporting member areextended. as at 9, and bent and formed to lit against the inner ring 7,or. as shown, one of these. flanges tits directly against the inner ring7 while the other flange of each supporting member overlaps or bearsagainst the outer side of the flange of the next adjacent supportingmember. The flanges of the supporting members are formed with slots 10which extend inwardly from their ends to receive the outer ring 8, theseslots being preferably so located that the outer ring 8 will beardirectly against the outer or overlapping flanges 9 of the supportingmembers. After the supporting members have been assembled with the innerand outer rings 7 and 8 in proper position at both ends of the holder,each of the inner rings 7 is expanded by a tube expander or othersuitable implement until the outer ring 8 has been put under tension.The ends of the supporting members will be firmly compressed and thusheld between these two rings.

A pervious holder constructed as shown in Figures 4, 5 and '6 may bedirectly inserted into a package of yarn or other material by pushingthe package of yarn from a paper tube 11 or other suitable holder of thesame diameter as the pervious holder onto the pervious holder, and afterthe dyeing or other treatment has been performed, the package of yarn orother material may be transferred from the pervious holder onto a papertube as the tube 11,- or onto a wooden or otherdesired holder byendwise. displacement of the package, these operations beingrepresenttul in Figure 7. The insertion and removal of the perviousholder as described is made possible by constructing the supportingmembers so that they extend in parallel straight lines continuously orwithout interruption throughout the length of the holder so that thereare no edges or other obstructions upon which the yarn might catch. Inorder to insure proper registration between the pervious holder and thepaper tube or other holder from or to which the package is to betransferred, the mandrel of the paper tube or the wooden holder may havea stem 12 thereon which is located concentrically with its axi and is ofa diameter to closely fit into theinner ring 7 of the pervious holder.

The present invention provides also a method whereby a paper tube or awooden or other holder may be removed from a package of yarn or othermaterial and a pervious holder of any of the types heretofore used maybe inserted into the package preparatory to dyeing or other treatmentthereof, without the necessity of unwinding and rewinding the yarn orother material. This is accomplished by the use of a paper tube. such asthe tube ll, Figure 7, or a wooden or other holder upon which yarn iswound, which tube or holder has a diameter substantially equal to thatof the pervious holder which is to receive the package, the pervioustube being placed'with one of its ends againstamlcentertul coaxiallywith the paper tube or wooden holder, and while the two holders are insuch relation, the pervious holder is pushed into the package andcoincidently the paper tube or wood on holder, is pushed. out of thepackage, the package of yarn being thus transferred from the paper tubeor wooden holder to the pervious holder without the necessity ofprelimiembodiment of theholder wherein the supporting members 13, whichextend parallel to and are suitably spaced circumferentially of theholder and form a central interior axially extending chamber ofpassageway within them are constructed from strips of sheet metaldoubled or folded transversely to give them a channel form incross-section, but the ends of the supporting members are drawn orformed into terminal flanges 14 which are curved .to fit against theouter circumference of an inner ring 15, and these terminal flanges ofthe supporting members'are encircled by an outer ring 16 which, in thisinstance, is smaller in diameter than that of a cylinder which includesthe yarn-supporting edges of the supporting members. After the terminalflanges of the supporting members have been assembled, so that they liebetween the inner and outer rings 15 and 16, the inner ring 15 isexpanded by a tube expander -or other suitable implement until the outerring 16 has been put under tension. The terminals of the supportingmembers will then be secured firmly by the clamping action produced bythe outer ring which is under tension and tends to contract upon theinner ring.

The intermediate portions of the supporting members in this embodimentof the'invention, as well as in the other embodiments thereof hereindescribed, may be stiffened by a reinforcement which will assist thesupporting members in sustaining compression exerted on theiryarn-supporting surfaces, and will maintain the intermediate portions ofthe supporting members in proper circumferentially spaced relation. Asshown in Figures 10 and 11, this reinforcement may consist of a ring 17which may be made of sheet metal of appropriate thickness and havingbends 18 formed therein at points in its circumference which correspondwith the circumferential spacing of the supporting members of theholder, so that when the supporting members are assembled, eachsupporting member will straddle or receive one of these bends 18 of thereinforcement, as will be clear from Figure 10. The reinforcing ringwill thus serve to connect the intermediate portions of the supportingmembers and thus assist them in sustaining compression forces actingthereon as well as forces tending to bend or deflect them out ofparallelism." In order to prevent displacement of the rein forcingmember in a direction longitudinally of the holder, the inner edges ofthe flanges of the supporting members may benotched, as indicated at19,to receive the reinforcing ring.

In this form of holder, the package of yarn may be readily" transferredtherefrom onto 2.

I paper tube, wooden bobbin or other substitute holder by pushing theyarn endwise, as there are. no portions of the holder larger indiameter-than that of the supporting members, so that removal of theyarn past the ends of the holder will not be obstructed.

Figures 12, 13 and 14 illustrate another construction of holder similarto that shown in Figures 1, 2 and 3 but which enables it to be removedfrom as well as inserted into the package of yarn without requiringunwinding or rewinding of the yarn. In this instance, the ends "of thesupporting members tween the lugs receives the portion of this ringwhich intervenes the notches 3a, but the outer ring 6a, instead ofextending around the outside of the supporting members, is fitted intoslots 16 formed in the ends of the supporting members. By thisconstruction, the outer ring does not obstruct the endwise movement ofthe yarn package along the edges of thesupporting surfaces or in otherwords, the yarn-engaging surfaces of the supporting members are straightand continuous or uninterrupted throughout their lengths, and hence theholder may be inserted axially into and removed from the yarn packagewithout obstruction and substantially without friction, thus avoidingthe necessity of unwinding or rewinding the yarn prior or subsequenttoits *dyeing or other treatment. The ends of the supporting members maybe secured by the clamping action exerted upon them by the contactingtendency of the outer ring, as in Figure 1.

In the construction shown in Figures 15, 16 and 17, the supportingmembers 13a which form a central interior axially extending chamber orpassageway within the holder are similar to those shown in Figures 8, 9and 10, the ends thereof being so shaped that they merge from thechannel form into relatively flattened but arcuate port-ions of a radiusto conform with the outer periphery of the inner ring 15a so that theends of the supporting members will" seat closely against the innerring. The longitudinal edges of these arcuate portions, however, areformed with lugs 20 which are turned inwardly, and the inner ring isformed with notches 21 in its opposite edges to receive these lugs, theedges of the arcuate portions having-recesses 22 be tween the lugs toreceive the portions of the inner ring which intervene the notches 21.Relative endwise displacement of the supporting members and the innerring is thus effectively prevented. The outer ring 1611 cooperates withthe inner ring 15a to secure the ends of the supporting members,exp-anding of the inner ring as previously described, producing aclamping action between the rings which firmly secures the supportingmembers in place.

Holders embodying the present invention may be used for various purposesbut they are particularly adapted to hold packages of yarn inproper formand condition to enable the yarn to be dyed. These holders having thepackages of yarn thereon may be placed in any suitable dyeing apparatusof the general class employed for this purpose, an example of a dyeingapparatus suitable for the purpose being shown and described in LettersPatent No. 1,052,817, granted February 11, 1913, the ends of-each yarnpackage receiving axial pressure acting in opposite directions, as, forexample, by compressing the package endwise between elements of theapparatus to form fluid-tight connections at these points which willcause the circulating dye liquor to pass either from the centeroutwardly through the yarn or vice versa. The b axial compression thusimposed on the package will not hinder or interfere with the properpassage of the dye liquor through the yarn as the yarn will becompressed uniformly, and, moreover, the yarn supporting sur-- faces onthe holder are of such relatively small areas that the flow of the dyeliquor 4 through the holder and between the holder and the yarn is notappreciably impeded. Furthermore, the holder is incompressible p axiallyso that axial compression of the yarn thereon may take place withoutinterference by the holder and the nature of the engagement of the yarnwith the holder is not altered. In consequence, the yarn during thedyeing operation, is held in such condition.

as will insure uniform and thorough .dyeing of the yarn.

By providing the holder with yarn-engaging surfaces which are straightand continuous or without interruption throughout the length of theholder, .the operation of inserting the holder into the yarn package orremoving the holder therefrom may be performed easily and quickly andwithout damage to the yarn. .The continuous or uninterrupted nature ofthese yarn-engaging surfaces does not become disturbed during the use ofthe holder, especially as the holder is not compressible or expansibleaxially, or. otherwise deformable in a manner that would ing the ends ofthe supporting members by a clamping action produced by the contractingtendency of the outer ring, permanence in the securing of the parts ofthe holder is attained, there-being no opportunityfor the parts tobecome loose relatively to one another as the inherent elasticity of theinner and outer rings while under stress will compensate 'ing for anychanges which would otherwise tend 'to cause looseness between the partsof the ting the ends of said members at their outer sides to clamp saidmembers together.
